Baby movement?

I’m 18 weeks 5 days pregnant with my first baby I’ve seen so many different things about baby movement and when they could feel their babies I definitely especially at night feel like twinges or maybe like pops lol I’m not sure how to explain but it’s hard for me to tell if it’s baby or not and I’ve been anxious about not feeling anything consistent I even seen a lady on tiktok who’s 19 weeks said she seen her baby kick from the outside already. I know we are all different but just anxious as a first time mom! Lol
